I'm not going to watch it again to find you timestamps (sorry), but I can assure you that in it other buildings (including the building with the camera, which is not the building which caught fire) are seen being shelled.
Edit: The information about radiation levels increasing does appear to have been false, but that's the only incorrect claim I've seen about what actually happened. There are also competing claims about how badly this reactor could melt down if it lost cooling, so at least some of those are incorrect. Which of these are intentionally false though is unclear.
1. This wasn't a small firefight. It was an hours long fight including numerous tanks, armored vehicles, rpgs, etc.
2. The training building caught fire, but it was far from the only piece of the complex shelled.
You can find the 4 hour long video of the fight here: https://www.youtube.com/watch?v=fYUT36YGOh8

I also believe that this footage/geolocation of damage within the complex is credible, though I have no hard proof of that: https://mobile.twitter.com/RespectIsVital/status/14998955944...
